MACHINERY FOR WRAPPING AND SECURING WRAPPERS AROUND BOXES, &c.

SPECIFICATION forming part of Letters Patent No. 570,615, dated November3, 1896.

Application filed April 3, 1894. Serial No. 506,162. (No model.)

"0 (LZZ 1071,0711, may concern.-

Be it known that I, ALBERT STEARNS, of the city of Brooklyn, in thecounty of Kings and State of New York, have invented a new and usefulImprovement in Machinery for Vrapping and Securing Vrappers aroundBoxes, Cakes, Packages, and other Articles of Merchandise, of which thefollowing is a full, clear, and exact specification.

A machine embodying this invention contains many of the featuresdescribed and claimed in my United States Patent No. 522,723, dated July10, 189i.

The object of this invention is to obtain a machine which is more simplein certain particulars than the machine which is the subject of saidpatent and which in certain ways is more effective.

To enable others skilled in the art to make and use my invention, I willfirst explain its construction so far as it is new withreference to theaccompanying drawings, and afterward point out in claims the essentialfeatures of its novelty.

Figure 1 represents a longitudinal elevation of a complete machineembodying my invention, one of the side frames being omitted to exposethe working parts to view and some of the shafts being in section. Fig.2represents a central section taken parallel with the view, Fig. 1, ofsome of the principal parts of the machine. Fig. 2 is a plan view ofwhat I call the wrapper-placer. Fig. 2 isa side view of one of thewrapper-depressing stops. Fig. 3 represents a transverse sectional viewtaken on the line 3 3 of Fig. 2. Fig. 4 represents a rear elevation ofthe feed-box from which the wrappers are supplied and of the partsthereunto appurtenant and adjacent. Fig. 5 represents a horizontalsection in the line 5 5 of Fig. 2. Fig. 6 represents an elevation takenat right angles to the view, Fig. 1, of certain parts shown at theright-hand end of that figure and to be hereinafter explained. Fig. 6*represents a side view of one of the cams, to be hereinafter described.Fig. 7 represents a horizontal section of what is termed the rotarycarrier and a plan of the dies for gluing the finally-folded-in ends ofthe wrappers. Fig. 8 represents a face view of one of the gluing-dies.Fig. 9 represents a side view of part of the rotary carrier and one ofthe folders for performing the final folding in of the ends of theWrappers. Fig. 10 represents a plan of the two folders last mentioned.Fig. 11 represents a vertical section taken at right angles to the View,Fig. 1, in the line 11 11. Fig. 12 represents a vertical section takenat right angles to the view, Fig. 11, in the line 12 12 of that figure,and viewed from the left thereof. Figs. 13, 14, 15,16, 17, and 18 areper-' represent nothing new and illustrate nothing more than operationssimilar to those performed by the machine which is the subject of mypatent hereinbefore referred to; but

I have not considered it superfluous to introduce them herein, becausethey will assist me in the explanation of the operation of my presentinvention.

1 will now proceed with the description of the machine.

C O designate an upright framing, on the top of which is supported thereceiving-table D, and in the'sides of which, at some distance below thesaid table, are supported the ends of the horizontal shaft E, of thereceivingwheel or rotary carrier'E, which, as here represented, rotatesupon the said shaft, which is stationary. The upper part of this carrierE, including one of the pockets e thereof, projects into an opening d inthe said table and to the level of the upper surface of the latter, asshown in Fig. 2. This opening (Z extends backward far enough, and iswide enough to allow the passage within it of the box G, in which anumber of wrappers g are placed one above another. I

To provide,v for the intermittent rotation of the rotarycarrierE, in thedirection of the arrow shown upon it in Figs. 1 and 2, to present itspockets 8 successively within the opening ICO pawl 6, (see Fig 1,carried by a lever E which.

works on a fulcrum 8 near the bottom of the machine. To this lever E isconnected one end of a rod 6", the other end of which is operated uponby a cam on a shaft S, which also carries other cams for operatingdifferent members of the machine. This cam is not here represented, butit is sufficient to say that it and the parts upon which it operates toproduce the rotation of the rotary c'arrier are the same as thoseheretofore used for the same purpose, as described in my aforesaidpatent.

To provide for locking the rotary carrier every time it arrives in theposition hereinbefore mentioned, and represented in Figs. 1 and 2,,there are provided in one side of the said carrier, a series of holese", to be engaged by a stop pin (3 which projects from the face of thebar E (see Fig. 1,) which is suspended at its upper end from thereceiving-table. This locking device and the means of actuating it beingthe same as those heretofore used, need no further description here.

In order to prevent the rotary carrier from being carried by itsmomentum, after the action of the pawl e ceases, beyond the position forthe pin e to lock it,.there is applied to it a friction-brake 0. (SeeFigs. 1, 2, and at.) This friction-brake, instead of being constantlyheld against the carrier like the brake described in my aforesaidpatent, is only brought into operation at the intervals requiredforstopping the rotary carrier. This brake, which is bifurcated, asshown in Figs. 4 and- 5, is pivoted to one end of each. of two arms 0,the other ends of which are pivoted by a pivot to a bracket 0 affixed toa hanger D, which is dependent from the receivingtable D. This brakelies loose upon the carrier until the proper time for stopping it, whenit is depressed against the carrier by the action on the arm 0 of theeccentric portionof a shaft 0 which turns in bearings 0 providedcon thesaid bracket 0 the said shaft 2 being provided, for the purpose ofoperating the said eccentric, with an arm 0 Figs. 2 and 4,, on the lowerend of which is a pin 0 which is received in a slot 0 in an upward I 1extension provided on a rod (see Figs. 1, 4, and 5,) which isconnectedwith and moved the same rod which is described in my aforesaidpatent, for the purpose of operating the row-dresser f, partly operatingthe packageexpeller 0c, and will be hereinafter again referred to.

The feed-box G, in which is placed a pile of sheets 9 of the proper sizefor the wrappers,

is of horizontal sectional form and dimensions corresponding with thewrapper-sheets. It is open at the top and on the whole of the side whichis toward the rotary carrier. It is supported on and firmly secured tothe upper end of a screw G, (see Figs. 2, 4, and 5,) the said screwbeing itself supported in a nut, which is constituted by theinternally-screwthreaded central bore of a ratchet-wheel G the saidratchet-wheel being confined vertically in an opening g in thestationary hanger D before mentioned. The box G and the screw G beingprevented from turning by reason of the box fitting the opening cl inthe receiving-table, the boX is moved Vertically by the rotation of theratchet-wheel G The turning of the ratchet-wheel G to eifect the raisingof the box to bring the wrappers g to the proper level to be taken bythe wrapperplacer Jj (see Fig. 2) is effected by means of a pawl 9carried by a lateral projection 00 on the expeller 00. In order toprovide for the lowering of the box when all the wrappers have beentaken from it, the ratchet-wheel G is divided diametrically into twohalves, as indicated by the dotted outline g in Fig. 5 and as shown inFig. 2, sothat the nut can be opened to liberate the screw G and allowit to be lowered. )Vhen the nut is closed, it is held in a clamp 9 whichdoes not prevent it from turning. The two members of this clamp,resembling a pair of tongs, are pivoted to each other and to the hangerD by a fixed pin. g The outer extremities of these tongs are connectedby toggle-links g with the lower end of a lever 9 (see Figs. 1 and 4,)

which works on a fulcrum g in the hanger D, and the upper end of whichis connected by a short link with the arm g of a short rockshaft 9which. works in a bearing 912 on the receiving-table D. This rock-shaftis provided with a hand-crank 9 by which it may be manipulated above thetable for the purpose of opening and closing the clamp g to liberate thenut of the ratchet-wheel G from the screw and reengage it therewith whendesired.

The paste-die H, (see Figs. 1 and 2,) bywhich a streak of paste isapplied along the front edge of the top sheet or wrapper g in the box Gand by which the said edge is picked up high enoughto be taken hold ofby the wrapper-placer Jj, is like that described in my aforesaid patent,and therefore it and its operating parts need no further descriptionhere than is necessary to prevent their confusion with other parts ofthe machine. The said die, which may also be called the wrapperlifter,has an upward and downward movement as wellas an oscillating movement ina fixed guide H for the purpose of taking paste from a paste-roller Iina paste-trough I and transferring the said paste to the front edge ofthe sheet or wrapper and afterward picking up the sheet or wrapper bythe adhesion. of the paste. The upward and downward movement is producedby a lever'I-P, operated upon through a rod 7& by a cam H on the shaftS. The oscillating movement'is produced by a cross-head 1 which istermed a paste-die shifter and which is moved back and forth by devicesnot represented. It will be understood that the front edge of a sheet 9in the box G corresponds with the edge a of the wrapper shown in Fig.15.

The wrapper-placer J j, which takes the wrapper-sheet from the paste-dieH, is the same as that described in my aforesaid patent, except that ithas affixed to and projecting upward from the carriage J, the front partof which constitutes the lower member of its grippers J j, a gagerepresented as consisting of a row of pins, (see Figs. 2 and 2%) which Iwill further describe after such brief description of the wrapper-placerand means of operating it as I will first give for properly identifyingthem from other, parts of the machine.

The connected fingers j, constituting the upper member of the grippers,are pivoted, as shown in Fig. 2, by a pivot j" to the lower member J,and betweenthe members J j are placed springs 3' for the purpose ofclosing them. The member J has pivoted to it ahook j", to which isapplied a spring j for the pur pose of pulling the said hook over one ofthe cross-bars j, which connect the several fingersj. In Fig. 2 thishook is shown as behind the cross-bar j and out of engagement with it,soas to leave the grippers closed. Fig. 2 also shows one of thegripper-openers J under which the rearward projections j of the fingersj run for the purpose of opening the grippers when the wrapper-placerhas brought the wrapper to a proper position over the upwardly-presentedpocket 6 of the wheel. The cam J 5 on the shaft S for producing thebackward and forward movement of the wrapper-placer is shown in Fig. 6*.The said cam operates, as heretofore, through a horizontal bar J 3 on alever J having its fulcrum j in a bracket on the back of the framing O,the upper end of the said lever being connected by a rod J with theplate J, constituting the lower member of the wrapper-placer.

The gage 3*, hereinbefore mentioned, the addition of which to thewrapper-placer constitutes part of the present invention, is for thepurpose of insuring the wrapper-sheet being taken from the paste-die Hexactly at such distance from the upwardly-presented pocket of therotary carrier, and in such relation to the movements of thepackage-feeder K and package-placer L L, that the wrapper will becarried by the wrapper-placer exactly to the requisite position toreceive the package. I

It has been found in practice that in the placing of the wrapper-sheetsin the box G, although they may be of exactly the same size, their frontedges will not always be even with each other or in the same verticalline, and the consequence is that when they are simply lifted from thepile in the box by the adhesion of the paste-die H, and grasped by gagej* is designed to effect.

the grippers of the wrapper-placer inthe exact position towhich theyhave been lifted, they will not all be carried to the exact positionrequired, and therefore I have found it desirable that the positionswhich the uppermost sheets occupy in the box at the time they are liftedshould be a little in advance of that at which the grippers are, andthat after having been lifted they shall be pushed back far enough tobring their front edges to the exact place in which the grippers are totake them, and this pushing back is what the This gage is attached tothe lower member J of the grippers, and as it has to pass throughtheupper member thereof it is composed of pins which are arranged in arow between the upper gripper-fingers j. These gage-pins j* strike thefront edge of the sheet just before the the rotary'carrier by the returnmovement of the wrapper-placer.

In order to push the upper wrapper-sheets g in the box G far enoughtoward the wrapper-placer to require to be pushed backby the gage j*,-as above described, leaf-springs 3, Figs. 2 and 4, are attached to therear edge of the opening (I in the receiving-table and project into thebox through openings in v the rear thereof. These springs have theirfaces so curved or inclined just below the level of the upper sheets inthe box as to constitute elastic cams against which the rear I edges ofthe sheets are brought by the act of raising the box and so caused to bepushed forward by that act. For the purpose of loosening and separatingthe upper wrappersheets in the pile and insuring that only the top oneshall be taken bythe paste-die H, I provide, as shown in Figs. 2 and 4,an openingj in one side of the box G, and opposite this opening Iarrange a small air-jet or blast pipe 7' through which compressed airfrom any suitable source, controlled by a stop-cock j in said pipe,isblown intothe box and among the sheets therein. 7

()n the table D, some distance beyond the package-placer L in thedirection in which the wrapper is carried by the wrapper-placer, thereare what I call fwrapper-depressing stops 1), (see Figs. 2, 2 and 3,) ofwhich there is one near each side of the machine. These are for thepurpose of stopping the wrappersheets in the proper position When theyare liberated from the wrapper-placer and for the purpose of depressingthe forward edges of the said sheets toward the top of thereceiving-table D. These stops 1) consist ofplates of metal, the form ofwhich-is best shown in Fig. 2 and rest upon the receiving-table, but

IIO

are attached to two short fixed standards b 011 the said table by meansof screws 12 (see Fig. 2,) by which the said stops are adjustablelaterally, according to the width of the wrapper-sheets, that they mayact upon the said sheets near the side edges thereof, and laterallyoutside of those parts of the sheets which are outside of the grippers Jj of the wrapper-placer. The said stops have on their front edgesprojections 11 (see Figs. 2 and 2 the lower edges of which are curved orsloped in such manner, and are at such height, that the edge of thesheet in passing under them will be depressed, and the portions of theedges at Z), below the said projections and immediately above the tableD, are upright to serve as positive stops at the points where the frontedge of the sheet is to be brought by the wrapper-placer.

The package-feeder K and the packageplacer L L are like those describedin my aforesaid patent, and therefore will be herein described only sofar as is necessary to distinguish them from other parts of the machinein the drawings. The plate K of the package-feeder, to which thepackage-box k is attached and which works in horizontal guides K, hasattached to it a slotted rod K the slot k of which receives an upwardprojection k provided on the rod J, hereinbefore described, the saidprojection, by its action against the ends of the slot k producing thenecessary movement of the package-feeder back and forth. Thepackage-placer is operated by the lever L a portion of which is shown inFig. 2, connected by a rod L with its plunger L. It is not necessary toshow the cams and connections for operating this lever, or to say moreabout them here than that they are the same as those described in myaforesaid patent.

, The folder M m, by which the edge a (see Figs. 13 and 14) of thewrapper is turned in, is the same as that shown and described in myaforesaid patent, consisting of a blade m (see Fig. 2) and a lever M, bywhich the said blade is carried, the said lever being arranged tooscillate upon the shaft E of the rotary carrier. As this lever may beoperated by the same cam and connections as are described in myaforesaid patent, it is not necessary here to repeat the illustrationand description of those parts.

For the turning over of the edge a (see Fig. 13) of the wrapper to thecondition shown in Fig. 14 I have represented in Fig. 2 the same rollerN as is shown for the same purpose in my aforesaid patent, the saidroller being at tached to the wrapper-placer.

The top tuckers, for turning in the edges a of the wrapper over the endsof the package, as shown in Fig. 15, and at the same time give form tothe side tucks a 60 are like those in my aforesaid patent-that is tosay, they consist of two thin plates 19', (shown in Fig. 2,) one on eachside of the rotary carrier, having a movement radial to the carrier inIn this machine the rock-shaft P,

oscillating motion described in said patent for the purpose of tuckingor folding in the side tucks a as represented in Fig. 16, have also aslight longitudinal movement toward and from the rotary carrier, in adirection parallel with the axis thereof, for the purpose of bringingthem closer to the rotary carrier preparatory to their movement by whichthe tucks a are folded in and of afterward taking them out of the way ofthe tucks and the carrier preparatory to their return oscillatingmovement. The oscillating movement of the said rock-shaft q and wingtuckers is here represented as produced in the same manner asheretofore. The groove of the cam Q for producing the said movements ofthe said tuckers is shown in dotted outline in Fig. 1. This cam operatesupon alon gituclinally-moving bar Q which is supported near the cam in arocker Q and works through a fixed guide Q on the framing. This barconnects with one arm, Q of a rock-shaft Q working in fixed bearings.two other arms, Q, which are connected b two rods q with two slidingtoothed racks q one on each side of the machine, which work instationary guides g and which gear with pinions (1 on the saidrock-shaft q. The longitudinal movement of this rock-shaft q, for thepurpose of making the wing tuckers q ap* proach and recede from therotary carrier, is produced by an oblique groove q (see Fig. 3) in eachrock-shaft and a fixed pin g, which is inserted through the box of itshanger q, and which projects into the said oblique groove. 7

It has been hereinbefore referred to as pa of this invention that therock-shaft P for operating the top tuckei's p derives its motion fromone of the rock-shafts g. This is effected by a crank (see Figs. 2 and 3on one end of the said rock-shaft, the wrist o the crank working in aslot (1 in an arm P, which is aflixed to the rock-shaft 2 the said slotbeing partly straight and partly curved, as shown in Fig. 2.

The slide-tuckers r, by which the side tucks a (see Figs. 16 and 1'7)are turned or folded in, are, like those represented and described in myaforesaid patent, attached to slides T, which work in fixed guides 7,attached to the framing of the machine; but instead of being operated bya special cam on the rock-shaft S, as described in that patent, theyderive mo- The said rock-shaft has.

tion in a more simple way from the rod J hereinbefore described, whichforms part of the mechanism for operating the wrapperplacer,-for whichpurpose the said rod has affixed to it, as shown in Fig. 1, anobliquelyslotted yoke or cam R, which is affixed to the said rod, andwhich receives within its slot.

a pin 1' on the arm 0" of a rock-shaft N, which is furnished with twoother arms, 4 which are connected, respectively, by the rods 1* with thetwo tucker-slides 'r. The rods 7' and their connection with the cam-yokeR on the rod J are also shown in Fig. 6.

U U, Figs. 1, 7, and 8, are dies which serve both to flatten the bottomtucks a and to apply glue to the inner faces thereof. These dies arelike what are called the glue-dies in my aforesaid patent, and have thesame movements between the rotary disk glue-feeders s and the bottomtucks of a package while the latter are spread out, as shown in Fig. 7,against the two stationary segment-plates W, which are arranged 011opposite sides of the rotary carrier E. )Vhat are called thepressing-dies in my aforesaid patent are now dispensed with, and thedies U are not only made to paste the end tucks, but also to press andflatten them. The reciprocating and oscillating shafts U which carry thedies U, derive their reciprocating movements, as heretofore, from therock-shaft U (see Fig. 1,) which carries forked arms U7 engaging withgrooved collars 21 on the said shafts U The means for producing thereciprocating movement of this rock-shaft being old, need not be hereindescribed. The oscillating movements of the said shafts U instead ofbeing produced bya specialcam on the rockshaft S, are derived in a muchsimpler way from the same rod J hereinbefore mentioned, through anupright rock-shaft U, (see Figs. 1 and 6,) which works in hearings inbrackets aflixed to the main framing, the said shaft deriving its motionfrom the said rod J 3 through a laterally-projecting arm U, projectingfrom the said rod and engaging with a pin U projecting upward from thearm U on the rock 'shaft. The said rock-shaft U carries another arm, U,which is connected with and gives the necessary motion to the rack-barU, (see Fig. 6,) on which are the two toothed racks engaging with thetoothed segments a on the die-shafts U It will be understood from theforegoing description that the one cam J 5 operates the package-feeder,the wrapper-placer, and the slidedies 1' and produces the swingingmovement of the glue-dies, thus simplifying the machine by dispensingwith two of the cams and other complex mechanism heretofore used.

As a part of this invention I also dispense with the swinging bottomtuck-closers heretofore used and the mechanism for operating them bysubstituting for the said tuckers a simple devicewhich forms part of oris an adjunct to the curb W, within which considerable portions of thecircumference and sides of the rotary carrier is inelosed, the said device being made to close in the said tucks by the mere act of rotationof the carrier. This device is illustrated in Figs. 7, 9, 10, 19, and20, Fig. 19 representing a section of the curb in the line 19 19 of Fig.10, and Fig..20 representing a section in the line 20 20 of Fig. 10.Just below the narrow openings i), (see Fig. 7,) provided in the sidesof the said curb W for the protrusion of the bottom tucks a against thefaces of the segment-pieces XV, there is provided in each side of thesaid curb a wider lateral opening 1:, which at its entrance is of thefull width of the curb, as shown in Fig. 9, and is gradually contracteddownward in the direction away from the axis of the carrier to a point712. The portions of the sides of the curb on the inner sides of theseopenings 'v' or nearer the axis of the carrier of the rotary carrierform outwardly-flanged tongues t the flanges v of which, at the upperends of the tongues and at the entrances to the openings '0', are flatand stand at right angles to the side of the curb, as shown in Fig. 10,but the said flanges gradually assume a curvature, as shown in Fig. 19,and become narrower until they are finally merged into the side of thecurb at the point 1: at the bottoms .of the openings 17'', where thetongues have the full width of the sides of the curb. In order tostiffen the'said tongues 11 and provide for a certain degree of lateraladjustment thereof, Ihave represented (see Figs. 9 and '10)bracing-brackets r affixed to the sides of the curb XV, having screwedthrough them set-screws US, which press against the sides of the saidtongues.

The operation of closing the tongues by the rotation of the carrier isas follows: As the wrapped package, with the top tucks a and side tucksa a of the wrapper turned in, ar-

rives at the entrance to the openings '0' in the sides of the curb theoutwardly-projecting tucks (t enter the said openings and projectoutward against the flat upper portions of the flanges v of the tonguest as shown in Fig. 10. Then as the rotation is continued the said tucks(0 following the curvature of the flange o and coming within the widerparts of the tongues 7J3, as shown in Fig. 19, are gradually turnedinward until, as they arrive at the lower and wider portions of thetongues, they are drawn entirely within the openings '1," and broughtwithin the widest portions of the tongues at the bottom thereof and intothe curb and closed against the. side tucks a (L in which condition theyare carried by the carrier through the curb W to the exit-trough whencethe packages are taken by the expeller :0, hereinbefore mentioned, anddeposited upon the deliverytable F.

The package-expeller a: is like that heretofore used consisting of areciprocating rake. The said expeller receives its movement to- .ward.the rotary carrier. for taking the wrapped packages from the upwardprojeciion w" on the rod as hereinbefore referred to in the descriptionof the mechanism for raising the box, the said projection or acting upona lateral projection 00 (see Figs. 1 and 5) on the said expeller. Theoutward movement of the expeller to draw the wrapped packages into andthrough the trough is effected by a projection 00 on the periphery ofthe cam QZwhich operates the wing tuekers, the said projection 00operating against a roller 00 on a lever ac which is connected with theexpeller by a link a The row-dresser, for pushing aside the rows ofpackages delivered through the trough V upon the receiving-table F,consists of a straight bar or plate f, such aswas described in myaforesaid patent, having a reciprocating motion across the table or atright angles to the planes of revolution of the rotary carrier and tothe direction of the delivery of the wrapped packages upon said table.As the said row-dresser is operated in the same way as described in thatpatent Ihave not thought it necessary to illustrate herein the whole ofits operating mechanism and will only describe what is shown of suchmechanism sufficiently to identifyit from other parts of the machine.The row-dresser f itself is only visible in Fig. 11, where it is shownin section as constructed of angle-iron. Its advance movement, by whichit pushes aside the rows, is obtained from the rod .00 hereinbeforedescribed and shown in transverse section in Fig. 11, the said barcarrying a pawl f which operates upon a ratchet-wheel f upon an uprightrotary shaft F, and the said ratchetwheel carrying a cam fflwhichoperates upon a roller f attached to a slidefiwhich works in aguide-groove f in the bottom of the receiving-table,the said slidefbeing connected with a bracket-arm f rigidly attached to the row-dresserf. The return movement of the row-dresser is obtained from a cam offsetF 011 a cam L on the shaft S, the said cam operating upon the lower endf of alever,which works on a fulcrum F and the upper end of which isconnected by a rod F with the bracket-arm f.

An important feature of myinvention consists in what I call apoint-holder, for the purpose of holding in the bottom tucks or points aof the wrappers until the glue by which they are secured to the sidetucks a a is thoroughly dried. This point-holder consists, as shown inFigs. 1, 11., and 12, of a series of boards T and endless chains T,carrying the said boards, the said chains being carried bysprocket-wheels T T on shafts which rotate freely in standards T",erected upon the receiving-table F, the direction of the run of the saidchains being across the table and at right angles to the rows ofpackages delivered thereon, and the length of the boards being parallelwith the direction of the rows. The said boards T, which are pivoted tothe said chains to swing freely, are at a distance apart exactlycorresponding with the length of the wrapped packages measured throughtheir bottom tucks or points a, so that said boards may interposethemselves between and separate the rows of packages, as shown in Fig.11, where one package of each of several rows is represented between thesaid boards, and

where it will be seen that the lower runs of the chains are parallelwith the table and that the lower edges of the boards on those parts ofthe chains run close to the receiving-table F. The upper runs of thechains have provided for them, between the sprocket-wheels T T guides z,and below these guides 25 are guides upon which the lower edges of theboards rest, as shown in Fig. 12, as they pass backward in the upperruns of the chains. In order to support the said boards as they fallover the sprocket-wheels T and until the proper time for them to fallbehind the last row of packages which has been deposited on thereceiving-table, a stop i is attached to the row-dresser. To explain theoperation of this point-holder, I will suppose that a row of wrappedpackages has just been placed between the two boards T nearest therow-dresser f and that the row-dresser is just beginning to moveforward, as shown in Fig. 11. As the row-dresser advances it pushesforward the point-holder and the several rows of packages 011 the tableF between the boards T in the lower runs of thechains, the boards T inthe upper runs of the chains in the meantime running backward on theguides '6 until one of the latter boards passes the extremity t" of saidguides 15. This last-mentioned board then drops onto the stop i providedon the row-dresser,

and there remains during the return movement of the row-dresser untilthe latter in completing said movement takes the stop i clear of thesaid board, which is then allowed to drop to the upright position infront of the row-dresser ready for a fresh row of packages to bedelivered between it and the next board in advance of it before the nextadvance movement of the row-dresser, by which all the packages on thereceiving-table are pushed onward, while the several rows are keptseparated by the boards between which the bot: tom tucks or points a oftheir several wrap pers are held closed.

The cam-shaft S, from which all parts of the machine derive theirmotion, may have rotary motion given to it by any suitable means.
